Human migration

Human migration is the movement by people from one place to another with the intentions of settling temporarily or permanently in the new location. The movement is typically over long distances and from one country to another, but internal migration is also possible. Migration may be individuals, family units or in large groups.[2]

Nomadic movements are normally not regarded as migrations as there is no intention to settle in the new place and because the movement is generally seasonal. Only a few nomadic peoples have retained this form of lifestyle in modern times. Also, the temporary movement of people for the purpose of travel, tourism, pilgrimages, or the commute is not regarded as migration, in the absence of an intention to live and settle in the visited places.

Migration statistics

Many estimates of statistics in worldwide migration patterns exist. The United Nations Statistics Division also keeps a database on worldwide migration.[4] Recent advances in research of migration via the Internet promise better understanding of migration patterns and migration motives.[5][6]

The World Bank's Migration and Remittances Factbook of 2011 lists the following estimates for the year 2010: total number of immigrants: 215.8 million or 3.2% of world population. In 2013, the percentage of international migrants worldwide increased by 33% with 59% of migrants targeting developed regions.[7] Almost half of these migrants are women, which is one of the most significant migrant-pattern changes in the last half century.[7] Women migrate alone or with their family members and community. Even though female migration is largely viewed as associational rather than independent migration, emerging studies argue suggest complex and manifold reasons for this.[8]

Often a distinction is made between voluntary and involuntary migration, or between refugees fleeing political conflict or natural disaster vs. economic or labour migration, but these distinctions are difficult to make and partially subjective, as the motivators for migration are often correlated. The World Bank's report estimates that, as of 2010, 16.3 million or 7.6% of migrants qualified as refugees. At the end of 2012, approximately 15.4 million people were refugees and persons in refugee-like situations - 87% of them found asylum in developing countries.[7]

Structurally, there is substantial South-South and North-North migration, i.e., most emigrant from high-income OECD countries migrate to other high-income countries, and a substantial part (estimated at 43%) of emigrants from developing countries migrate to other developing countries. The United Nations Population Fund says that "[w]hile the North has experienced a higher absolute increase in the migrant stock since 2000 (32 million) compared to the South (25 million), the South recorded a higher growth rate.[7] Between 2000 and 2013 the average annual rate of change of the migrant population in the developing regions (2.3%) slightly exceeded that of the developed regions (2.1%).[7]

The United Nations reported that 2014 had the highest level of forced migration on record: 59.5 million individuals, caused by "persecution, conflict, generalized violence, or human rights violations", as compared with 51.2 million in 2013 (an increase of 8.3 million) and with 37.5 million a decade prior. As of 2015 one of every 122 humans is a refugee, internally displaced, or seeking asylum.[11]National Geographic has published 5 maps showing human migrations in progress in 2015 based on the UN report.[12]

Theories for migration for work in the 21st century

Overview

There are a number of reasons why people choose to migrate to another country. Globalisation has increased the demand for workers from other countries in order to sustain national economies. Known as "economic migrants," these individuals are generally from impoverished developing countries migrating to obtain sufficient income for survival.[13] This income is usually sent home to family members in the form of [13] Socio-cultural and geo-historical factors also play a major role. In North Africa, for example, being an immigrant in Europe is considered a sign of social prestige. Moreover, there are many countries which were former European colonies. This means that many have relatives that live legally in Europe, who often constitute an important help for immigrants who have just arrived in a European country. Relatives might help for job researchers and accommodations. The geographical proximity of Africa to Europe and the long historical ties between Northern and Southern Mediterrean countries also prompt many to migrate.[15]

There are a number of theories to explain the international flow of capital and people from one country to another.[16]

Neoclassical economic theory

This theory of migration states that the main reason for labour migration is wage difference between two geographic locations. These wage differences are usually linked to geographic labour demand and supply. It can be said that areas with a shortage of labour but an excess of capital have a high relative wage while areas with a high labour supply and a dearth of capital have a low relative wage. Labour tends to flow from low-wage areas to high-wage areas. Often, with this flow of labour comes changes in the sending as well as the receiving country. Neoclassical economic theory is best used to describe transnational migration, because it is not confined by international immigration laws and similar governmental regulations.[16]

Dual labour market theory

Dual labour market theory states that migration is mainly caused by pull factors in more developed countries. This theory assumes that the labour markets in these developed countries consist of two segments: tertiary, which requires high-skilled labour, and primary, which is very labour-intensive but requires low-skilled workers. This theory assumes that migration from less developed countries into more developed countries is a result of a pull created by a need for labour in the developed countries in their secondary market. Migrant workers are needed to fill the lowest rung of the labour market because the native labourers do not want to do these jobs as they present a lack of mobility. This creates a need for migrant workers. Furthermore, the initial dearth in available labour pushes wages up, making migration even more enticing.[16] A rapid change can be diagnosed in 21st century when labours from less developed countries are treated as high-skilled immigrants a they play a crucial role in tertiary segment.

The new economics of labour migration

This theory states that migration flows and patterns cannot be explained solely at the level of individual workers and their economic incentives, but that wider social entities must be considered as well. One such social entity is the household. Migration can be viewed as a result of risk aversion on the part of a household that has insufficient income. The household, in this case, is in need of extra capital that can be achieved through remittances sent back by family members who participate in migrant labour abroad. These remittances can also have a broader effect on the economy of the sending country as a whole as they bring in capital.[16] Recent research has examined a decline in U.S. interstate migration from 1991 to 2011, theorising that the reduced interstate migration is due to a decline in the geographic specificity of occupations and an increase in workers’ ability to learn about other locations before moving there, through both information technology and inexpensive travel.[17] Other researchers find that the location-specific nature of housing is more important than moving costs in determining labour reallocation.[18]

Relative deprivation theory

Relative deprivation theory states that awareness of the income difference between neighbors or other households in the migrant-sending community is an important factor in migration. The incentive to migrate is a lot higher in areas that have a high level of economic inequality. In the short run, remittances may increase inequality, but in the long run, they may actually decrease it. There are two stages of migration for a worker: first, they invest in human capital formation, and then they try to capitalise on their investments. In this way, successful migrants may use their new capital to provide for better schooling for their children and better homes for their families. Successful high-skilled emigrants may serve as an example for neighbors and potential migrants who hope to achieve that level of success.[16]

World systems theory

World systems theory looks at migration from a global perspectives. It explains that interaction between different societies can be an important factor in social change within societies. Trade with one country, which causes economic decline in another, may create incentive to migrate to a country with a more vibrant economy. It can be argued that even after decolonisation, the economic dependence of former colonies still remains on mother countries. This view of international trade is controversial, however, and some argue that free trade can actually reduce migration between developing and developed countries. It can be argued that the developed countries import labour-intensive goods, which causes an increase in employment of unskilled workers in the less developed countries, decreasing the outflow of migrant workers. The export of capital-intensive goods from rich countries to poor countries also equalises income and employment conditions, thus also slowing migration. In either direction, this theory can be used to explain migration between countries that are geographically far apart.[16]

Historical theories

Ravenstein

Certain laws of Ravenstein's (1834-1913) proposal in the 1880s. The laws are as follows:

urban residents are often less migratory than inhabitants of rural areas.

families are less likely to make international moves than young adults.

most migrants are adults.

large towns grow by migration rather than natural increase.

migration stage by stage.

urban rural difference.

migration and technology.

economic condition.

Lee

Lee's laws divide factors causing migrations into two groups of factors: push and pull factors. Push factors are things that are unfavourable about the area that one lives in, and pull factors are things that attract one to another area.[19]

Push Factors

Not enough jobs

Few opportunities

Inadequate conditions

Desertification

Famine or drought

Political fear or persecution

Slavery or forced labour

Poor medical care

Loss of wealth

Natural disasters

Death threats

Desire for more political or religious freedom

Pollution

Poor housing

Landlord/tenant issues

Bullying

Discrimination

Poor chances of marrying

Condemned housing (radon gas, etc.)

War

Pull Factors

Job opportunities

Better living conditions

The feeling of having more political and/or religious freedom

Enjoyment

An increasing number of Turks, the Netherlands’ largest ethnic minority, are beginning to return to Turkey, taking with them the education and skills they have acquired abroad, as the Netherlands faces challenges from economic difficulties, social tension and increasingly powerful far-right parties. At the same time Turkey’s political, social and economic conditions have been improving, making returning home all the more appealing for Turks at large. (pp. 94–99)

Climate cycles

The modern field of climate history suggests that the successive waves of Eurasian nomadic movement throughout history have had their origins in climatic cycles, which have expanded or contracted pastureland in Central Asia, especially Mongolia and the Altai. People were displaced from their home ground by other tribes trying to find land that could be grazed by essential flocks, each group pushing the next further to the south and west, into the highlands of Anatolia, the Pannonian Plain, into Mesopotamia or southwards, into the rich pastures of China. Bogumil Terminski uses the term "migratory domino effect" to describe this process in the context of Sea People invasion.[20]

Other models

Migration occurs because individuals search for food, sex and security outside their usual habitation.[21] Idyorough is of the view that towns and cities are a creation of the human struggle to obtain food, sex and security. To produce food, security and reproduction, human beings must, out of necessity, move out of their usual habitation and enter into indispensable social relationships that are cooperative or antagonistic. Human beings also develop the tools and equipment to enable them to interact with nature to produce the desired food and security. The improved relationship (cooperative relationships) among human beings and improved technology further conditioned by the push and pull factors all interact together to cause or bring about migration and higher concentration of individuals into towns and cities. The higher the technology of production of food and security and the higher the cooperative relationship among human beings in the production of food and security and in the reproduction of the human species, the higher would be the push and pull factors in the migration and concentration of human beings in towns and cities. Countryside, towns and cities do not just exist but they do so to meet the human basic needs of food, security and the reproduction of the human species. Therefore, migration occurs because individuals search for food, sex and security outside their usual habitation. Social services in the towns and cities are provided to meet these basic needs for human survival and pleasure.

Bauder's regulation of labour markets (2006) "suggests that the international migration of workers is necessary for the survival of industrialised economies...[It] turns the conventional view of international migration on its head: it investigates how migration regulates labour markets, rather than labour markets shaping migration flows."[22]

^India, Russia and the UK figure in both lists, as they have substantial immigration and substantial emigration, but also because the ranking reflects absolute numbers and thus favours large countries.
